The President is asked whether he will seek another term in office at the end of the episode by a reporter. The reporter repeats the question.
The question when repeated by the reporter is slightly different when the flash back is shown in the first episode of the next season.
The motorcade passes the National Cathedral on the way from the White House to the State Department. In fact, the State Department is only several blocks from the White House (due west of the Ellipse) while the National Cathedral is more than three miles away. Furthermore, the motorcade appears to pass directly past the front doors of the cathedral at full speed. While there is a paved area in front of the cathedral, the street is almost 200 feet from the entrance and the geography of the cathedral's close wouldn't permit that speed.
